Large-scale shield electric machine temperature sensor casing high-precision conical surface deep hole processing technology
Technical field:
The present invention relates to a kind of large-scale shield electric machine temperature sensor casing high-precision conical surface deep hole processing technologies.
Background technique:
Temperature sensor casing is the critical component of large-scale shield electric machine bearing measuring water temperature, it is desirable that when temperature sensor quilt It is properly attached to inside pipe casing, temperature about 83 DEG C 63.2 DEG C of Spline smoothing from room temperature to water temperature, lateral flow is on a sensor Any combination of 3914.4mm/s, temperature sensor and casing should be no more than 7 seconds reaction normals, can quick and precisely detect electricity The variation of machine bearing water temperature, so casing tube internal hole conical surface surface roughness is at least up to 3.2 μm, dimensional accuracy reaches high requirement There can be close compactness with the sensor end conical surface.Temperature sensor casing tube internal hole taper is 1 ° 30 ', and straight hole is having a size of φ 6.5mm tolerance 0.2mm, bottom taper hole minimum diameter are 4mm, entire hole depth 375mm, and drilling depth has reached the 94 of bit diameter Times, hinge conical hole is extremely difficult still more under so small aperture, and uses this temperature sensor casing high-precision conical surface deep Hole machined technique can be completed to process.
For High-precision Deep Hole cone face process, country's processing can only generally be processed using professional deep hole working machine, No matter roughness or position degree are unable to reach the requirement of nuclear power product to machine tool deep hole processing, and temperature sensor casing Hinge conical surface hole depth has reached 94 times of bit diameter, and the country is bored without such large-scale shield electric machine temperature sensor casing tube internal hole Face maturation processing method, demand casing can only carry out external buying, and procurement cycle is long, and there are uncertainties, therefore adopts With this temperature sensor casing high-precision conical surface deep hole processing technology, the conical surface deep hole machining of high-precision requirement is reached, has drilled Mode is stablized, and realizes the production domesticization of temperature sensor casing high-precision conical surface deep hole machining and is of great significance, and is also enterprise Industry save the cost improves machine tool utilization rate and production capacity.
Summary of the invention:
It is an object of the present invention to provide a kind of large-scale shield electric machine temperature sensor casing high-precision conical surface deep hole processing technology, Reasonable machined parameters, chip removal method and processing sequence are taken, connecting machine tool cooling system realizes that high-precision conical surface deep hole adds Work.To achieve the above object, scheme is as follows:
1) temperature sensor casing is fixed on numerical control five-axle machining center rotary table simultaneously centering；
2) adaptation deep hole drill guide hole is processed in temperature sensor box face；
3) deep hole drill processing temperature sensor sleeve straight hole size is used；
4) using apex point after the flat deep hole drill processing of flat bottom bit；
5) taper hole size is processed using the subland drill of 3 kinds of dimensions, starts lathe cooling system, select cutting parameter For revolving speed 340r/min tool feeding 8mm/min, start to process the depth until needs by the way of axis feeding, during which rank The terraced every feeding 2mm of drill bit carries out anti-bits cleaning drill bit；
6) cutting parameter is selected to bore for revolving speed 200r/min tool feeding 2.4mm/min to subland drill using flat bottom bit The apex point processing left behind hole, reaches flat purpose；
7) taper hole size is processed using the taper reamer of 3 kinds of dimensions, starts lathe cooling system, the choosing of first two taper reamer Selecting cutting parameter is revolving speed 45r/min tool feeding 2mm/min, the third taper reamer selects cutting parameter for revolving speed 38r/min Tool feeding 1.2mm/min to 0.6mm/min starts to process the depth until needs by the way of axis feeding, during which bores The every feeding 1mm to 2mm of reamer carries out anti-bits cleaning drill bit, starts to go deep into deep hole bottom using air hose before drilling every time to be passed through compression Air carries out purging cleaning.
The technology of the present invention effect:
Using motor temperature sensor casing high-precision conical surface deep hole processing technology of the present invention, sizes specification is used Subland drill and taper reamer select reasonable machined parameters and processing sequence, and guide hole is first processed on casing and processes straight hole Part reuses subland drill, flat bottom bit, and taper reamer processes conical surface deep hole size, during which carries out reasonable chip removal, uses The mode of axis feeding processes conical surface deep hole, and the type of cooling uses cutter inner cooling, so that the conical surface for having reached high-precision requirement is deep Hole machined, bore mode are stablized, and realize the production domesticization of temperature sensor casing high-precision conical surface deep hole machining and have great Meaning also improves machine tool utilization rate and production capacity for enterprise's save the cost.
For High-precision Deep Hole cone face process, country's processing can only generally be processed using professional deep hole working machine, Only simple using a type of drill bit or reamer, drilling depth can reach 70 times of bit diameter or so, and fraising is deep Degree commonly reaches 10 times of reamer diameter or so, and only processing straight hole is not processing conical surface deep hole, and temperature is much not achieved The requirement of sensor sleeve high-precision conical surface deep hole machining, hinge conical surface deep hole depth need to reach 94 times of requirements of cutter diameter, Process program without such maturation.
This temperature sensor casing high-precision conical surface deep hole processing technology needs to pay attention to the control to critical processing parameters, Since the interiors of products hinge small conical surface minimum diameter of conical surface deep hole diameter is only 4mm, hole taper is 1 ° 30 ', entire hole depth 375mm, cutter hinge conical surface hole depth has reached 94 times of bit diameter, especially to the dimensional accuracy after hinge conical surface deep hole, table Surface roughness, position degree requirement are very high, carry out very big difficulty to drilling, fraising work belt, must be to clamping cutter before processing Jitter values strict control, it is accurate to calculate cutter chip removal distance, first process taper hole size using subland drill in process Profile mitigates taper reamer stress burden, uses the flat apex point of flat bottom bit later, avoids taper reamer end face unbalance stress, finally The processing of the deep hole conical surface is completed using taper reamer.
